1 Claim. (012 51 125) This invention relates. .to newgand .useful,improvements and structural ITBfiIIBmBHtSlIIJfdI'BSS- ing machinesfor-bowling.-pins, ,and the principal object of the invention is toprovide a device of the character herein described, such as maybe"-conveniently and effectively employed for dress- -ing both, the basesurface and the lateralsurface of such pins.

A further object of the invention is to provide a dressing machine inwhich the bowling pin may be quickly and easily applied or removed andwhich may be conveniently manipulated.

Another object of the invention is to provide a dressing machine whichis simple in construction, which will readily lend itself to economicalmanufacture, and which is otherwise well adapted for the purpose forwhich it is intended.

With the above more important objects in view and such other objects asmay become apparent as this specification proceeds, the inventionconsists essentially of the construction and arrangement of parts asshown in the accompanying drawings in which:

Figure 1 is a top plan view of the invention, showing the same inreadiness for dressing the base surface of the bowling pins;

Figure 2 is a side elevation of the device illustrated in Figure 1;

Figure 3 is a top plan View, similar to that shown in Figure 1, butillustrating the invention in readiness for dressing the lateral surfaceof the pin;

Figure 4 is a side elevation of the device shown in Figure 3;

Figure 5 is a cross-sectional view, taken substantially from the planeof the line 5-5 in Figure 1, and;

Figure 6 is a perspective view of a bowling pin holder used in theinvention, showing the positional relationship thereof with respect tosome of the remaining components, illustrated in phantom lines.

Like characters of reference are used to designate like parts in thespecification and throughout the several views.

Referring now to the accompanying drawings in detail, the inventionconsists of a dressing machine designated generally by the referencecharacter I0, the same embodying and in its construction an elongatedbase plate or bed H, one end portion of which may be reduced in width,so as to form what may be referred to as a platform l2 for a suitableelectric motor IS.

The armature shaft M on this motor carries a faceplate-l5yandif desired,the bed I I may be formed-with a-"suitable recess 16 in order to ac--commodatethe lower portion of face plate, as

"will be clearly apparent.

-' The plate "I5 ,is provided at the center thereof "with a concaverecess I! which is adaptedto engage the rounded end portion IB of thebowling pin-l9. 'The'base portion 20 on the bowling "pin rotatablyengages a center point 2| of the tail stock 22, the latter being of themore-or-less conventional design and being removably secured to the bedII by virtue of a further recess 23 with which the bed is provided.

It should be understood that the tail stock 22 is adjustable, that is,the center point 2| may be projected or retracted longitudinally bymeans of a suitable hand crank 24 and also, that the position of thetail stock with respect to the recess 23 may be longitudinally adjusted,as indicated by the arrow 25,

In this manner, bowling pins of various lengths may be readilyaccommodated by the machine and the dressing operation of the lateralsurface of the pin is performed by simply applying sand 25 paper, or thelike, to the pins, while they are being rotated by means of the faceplate l5.

When the lateral surface of the bowling pin has been dressed, the basesurface 26 thereof may be subjected to a similar treatment, this beingachieved by removing the pin from its position between the tail stockand the face plate and placing the pin in a holder designated generallyby the reference character 21.

This holder is in the form of a unit separate from the machine itselfand consists of a pair of spaced parallel end pieces 23, rigidlyconnected together by means of a pair of lateral members 29 and a basemember 30. The configuration of the members 29, 30 will be clearlyapparent from the accompanying drawings, and it will be noted that theend pieces 28 are formed with suitable recesses so that the holder 21,as a whole, constitutes what may be referred to as a cradle for thebowling pin.

A guide bar 3| is secured to the bed by means of suitable screws 32, thebar 3| extending in parallel to the common longitudinal axis of the tailstock 22 and of the face plate I5.

The face portion of the plate 15 surrounding the recess I1 is providedwith a replaceable sanding disc 33 and accordingly, the dressing of thebase surface 26 may be effectively performed by simply positioning thepin [9 in the cradle or holder 21 and sliding the holder along the bed iI so that the surface 26 engages with the sanding 3 disc 33. It will benoted in this connection that since the side edges 34 of the cradle endpieces 28 are in engagement with the bar 3|, the latter will function asa guide for the cradle, whereby the dressed base surface will bedisposed at right angles to the longitudinal axis of the bowling pin, Inthis manner, the accuracy of the dressing operation is assured.

Since the holder or cradle 21 conforms substantially to the contour ofthe bowling pin, it

should be understood that separate holders or cradles are to be providedin order to accommodate both, the so-called candle pins as well as duckpins. However, the remaining components of the machine may beeffectively employed in association with pins of both types, andattention is again directed to the fact that the dressing of I thelateral surface as well as the base surface of the pin is performed bythe same machine and that in such manner, that the dressed base surfaceis disposed in a plane perpendicular orat right angle to thelongitudinal axis of the pin.

It is-believed that the advantages and use of the invention will beunderstood from the foregoing disclosure and accordingly, any furtherdescription thereof at this point is considered unnecessary.

While in the foregoing there has been shown and described the preferredembodiment of this 4 invention it is to be understood that minor changesin the details of construction, combination and arrangement of parts maybe resorted to without departing from the spirit and scope of theinvention as claimed.

What We claim as our invention is:

In a dressing machine for bowling pins, the combination of an elongatedbed having a flat upper surface, a rotatable abrading disc adjacent oneend of said bed, a guide bar provided at one longitudinal edge of saidbed and extending perpendicularly to theplane of said disc, and abowling pin receiving cradle slidably and removably resting on said bed,said cradle including lateral extensions engageable with said bar toguide said cradle toward said disc.
